Capacitive Dimmer switch circuit

Capacitive dimmer switch circuit shown in Figure 9. It is the use of capacitive reactance principle of alternating pairs made.

S When the position shown, normal light bulb E, namely the maximum brightness; when dial to position when Gushan string into 2VF capacitor C. Lamp brightness decreases E; when the time is set aside to busy , solid C, <e. , Larger capacitance, reduce the brightness of the fork of a small block; when the dial to position , light E off. c. , C Gallery using voltage 100V to f nonpolar oil paper capacitor, S to l 4 single-pole four-throw switch.
